If you followed Formula 1 in 2009 and 2010 you will probably recall the terms double diffuser and F-duct. However, unless you were in the aerodynamics department of an F1 team during that period you will probably only have a sketchy idea of how these devices actually produced the elusive, race-winning, downforce that is key to F1 success.

Time for some fluid dynamics news with a Computational Fluid Dynamics (CFD) slant. Check out how CFD was used to make hydraulic capsule pipeline predictions and simulate the flow through fish farming sea cages.

Symmetry is a simple but powerful concept that you can use to speed up your Computational Fluid Dynamics (CFD) simulations and reduce your memory requirements. Join me in an exploration of a simple symmetry case.

Pareto analysis usually reveals a golden 80-20 rule for squeezing performance out of things. In other words - it means the majority of the performance (80%) is typically governed by a minority (20%) of factors. Pareto analysis applies equally across many disciplines from sports (marginal gains anyone?) to product design.

Don't settle for Computational Fluid Dynamics (CFD) software that uses (abuses) facets (e.g., STL) as geometry. If your original geometry is analytic (CAD) then mesh it directly without the conversion to facets. Otherwise it's like you have to create two surface meshes. What's wrong with that? Plenty!

The spectacle that is the Tour de France (TdF) is all about aerodynamics - and you thought it was all about the bike. Virtually all tactics in the TdF are dictated by individuals or teams of riders attempting to limit their exposure to the 'wind', in order to minimize drag and therefore minimize the effort required to progress. There are some obvious and not so obvious tactics riders and teams employ to use aerodynamics to gain advantage.
